Both Grandstream and Sip trunk provider were extremely helpful but multiple calls were necessary to configure correctly. Once completed the system worked better than expected. Plan on 6-8 hours of programming and tech calls. Once done, sit back and relax and let it work.

Two draw backs are difficult to transfer calls and also see who else is using their extensions.Review by Medium size health care office(Posted on 5/11/16)

Cheap! But easy to get hacked

It's really cheap, but the security measure is very bad.
It's new machine, and not stable at this point of time.
At least wait 1-2 years to be stable for their security leak flaw.
